A 26-year-old man complained of swelling in the right parotid region of two months duration. Open biopsy at another hospital suggested osteogenic sarcoma. Pre- and postoperative chemotherapy (CDDP+THP-ADM) was administered. Hemimandibulectomy combined with neck dissection was performed. One and a half years later, the patient is alive with no evidence of local recurrence or metastasis.
